Highly Alloyed (i.e., Greater Than 10 Percent Alloying Elements) Patents (Class 148/621)
  • Coated metal article and method of coating
    Patent number: 3961993
    Abstract: Methods of coating metal articles to protect them from corrosion, and the products of such methods. Metal articles which have been electroplated with zinc, cadmium, nickel or chromium, or which have been phosphated, are chromated, and coated with a hydrophobic thermosetting polymer, and heated to convert the polymer to a hard, adherent film. Multiple polymer coatings may be applied prior to heat curing, and the corrosion resistance of the coating is thereby vastly improved.
